Natural Disasters will add a series of city-destroying emergencies to Cities: Skylines, which can occur unexpectedly during the game – or be manually triggered by mayors seeking a challenge or some sort of gruesome, vindictive pleasure. Buildings and infrastructure will be destroyed, fire can spread across locations, and countless lives may be lost unless players implement the right emergency plans and responses and keep an ear on the new radio alert system. Fans of Cities: Skylines will have the chance to overcome everything from massive fires to meteor strikes, and allow their friends to do the same with a new Scenario Mode, where custom challenges can be designed and shared through Steam Workshop.
